System-board LEDs
Use this information to locate system-board LEDs in the blade server.
You must remove the blade server from the BladeCenter unit, open the cover or
remove any optional expansion units, and press the light path diagnostics switch
(see “System-board switches” on page 16) to light any error LEDs that were turned
on during processing. Diagnosing problems using the light path diagnostic LEDs is
described in “Light path diagnostics” on page 183.
The following illustration shows the light path diagnostics panel on the system
board.
